FANUC A06B-6117-H205 Dual-Axis Alpha i Servo Module

Overview

The A06B-6117-H205 is a dual-axis Alpha i servo amplifier module used in FANUC motion systems that need a compact two-axis drive arrangement with stable output on both channels.

Public replacement listings consistently identify this model as AiSV-20/20, which places it in the Alpha i dual-axis servo family rather than in the spindle or power-supply sections of the cabinet.

In practical machine service, a module like this is usually chosen to keep an existing control system in its original drive architecture. That matters because dual-axis FANUC amplifiers are normally matched not only by voltage and current, but also by cabinet layout, communication structure, and the exact axis pairing already used on the machine.

For this reason, the most useful product-page positioning is technical and direct: this is a FANUC Alpha i dual-axis servo module for replacement, repair, and installed-machine support.

Public references also give the H205 family a clear electrical profile.

Listings commonly show 283–325/339 V input, 240 V maximum output, about 5 kW power context, and 6.5 A rated output current on both L and M axes.

That puts the module in the smaller symmetrical dual-axis section of the Alpha i servo range, which is useful when distinguishing it from mixed-capacity modules such as 20/40 or 40/80 classes.

Key Specifications

Why the AiSV-20/20 Class Matters

One of the most practical things about A06B-6117-H205 is that both controlled axes belong to the same output class. In real maintenance work, that symmetry helps the module fit machines that were originally built around equal-class paired axes.

It also makes the amplifier easier to identify against larger Alpha i modules that may look similar in cabinet photos but belong to a different current family.

Because it is a dual-axis module, buyers normally evaluate it as part of a complete machine drive structure rather than as an isolated electronic unit.

That is why exact model identity matters more than generic descriptions like “servo drive” or “motion amplifier.”

For industrial users, a correct AiSV-20/20 replacement is about restoring known machine behavior with minimal architectural change.

FAQ

Q1: What kind of product is A06B-6117-H205?
It is a FANUC Alpha i dual-axis servo amplifier module identified in public listings as AiSV-20/20.

In practical CNC use, it drives two servo axes from one amplifier unit and is typically sourced to support or restore an existing machine rather than to serve as a general-purpose stand-alone drive.

Q2: Why is the AiSV-20/20 designation important?
It tells the buyer that the module belongs to a specific Alpha i dual-axis class with the same current level on both axes.

In replacement work, that detail is important because many FANUC machines are built around a fixed cabinet layout and a fixed servo class, so matching the family correctly helps avoid application mistakes.

Q3: Are the 5 kW and 6.5 A figures useful in real selection?
Yes. Those values help show that this is a relatively compact dual-axis Alpha i module rather than a higher-capacity 40/80 or 160/160 class unit.

For service engineers, these numbers are useful because they provide a quick way to distinguish the amplifier from nearby family members and confirm whether it fits the installed axis load range.

Q4: Is this mainly a replacement and service product?
Yes. Public sources present it through CNC parts, repair, and exchange channels, which is typical for installed-drive hardware.

Buyers normally source this model to keep an existing machine running, preserve the original control architecture, and avoid redesigning the amplifier arrangement around a different family.

Q5: What should buyers verify before ordering?
Buyers should verify the exact part number on the installed unit, the AiSV-20/20 family designation, the two-axis architecture, and the machine’s original drive and communication layout.

For FANUC amplifiers, correct family and axis matching are usually more important than broad category similarity.
